Expert Solution

1. Man Whitney U test

It is the non paramatric test alternative to independent sample t test in paramatric. It is used for the comparison of median of two independent sample. This test used when the sample doesn't follow Normal distribution.

2. Kolmogorov Smirnov test

This test is used for testing the normality for two samples.

While conducting the parametric tests for checking the normality assumption this test is widely used.

3. Kruskal Wallis test

For the comparison of mean of several populations i.e more than two populations we use ANOVA if the assumptions are satisfied. If the sample doesn't follow any assumption then the alternative test Kruskal Wallis is used for comparison of several populations median.

4. We know for the comparison of several population means we use ANOVA. If we have the two independent variables then two way ANOVA is used .Two way ANOVA is also helpful in checking significance of interaction effect of two variables too.
